Ham Radio AA-908 SWR Antenna Analyst

Features Manual and automated antenna analysis based on SWR and complex impedance measurements Operating modes provided for measurement of network impedance, and inductors and capacitors Operating mode provide RF signal source at output serves as external VFO and test signal Powerful 8-bit microcontroller controls all aspects of the operation High-precision, low power DDS signal generator is used as rock-solid signal source Internal reflectometer measures forward, reflected and impedance signals Automatic scanning results displayed as frequencies with lowest SWR Configurable frequency scanning limits and step sizes Manual control option displays SWR and complex impedance at selected frequencies Audible tone indicates resonance - lower tone indicates lower SWR May be enabled/disabled. Serial port connects to PC for field-upgradable software Serial port connects to PC for uploading and graphical display of measurement data Battery-operated for convenient field use, or can use external 9-16V for bench operation Other uses of the Instrument. Adjust antenna tuners and determine loss. Measure coax transmission line (SWR, length, velocity factor, approximate Q and loss, resonant frequency, and impedance). Measure and determine optimum settings for tuning stubs: SWR, approximate Q, resonant frequency, bandwidth, impedance. Determine characteristic impedance of transmission line.

Determine length of ¼ and ½ wave phasing lines. Measure magnetic loop resonance and SWR.
